Kate Middleton and Prince William Thank Anniversary Well-Wishers in the Classiest Way Ever

Kate Middleton and Prince William are just so perfect, right? It’s like every time we think they’ve reached peak perfection, we get another awesome glimpse into their lives. Most recently, the couple celebrated their sixth wedding anniversary on April 29 (which means the couple had a Taurus wedding, further proof that the royals do enjoy the finer things in life). To thank their fans, they shared a euphoric-feeling throwback photo from their nuptials on Instagram—and hey, as fans, we’ll take any access to the royal wedding we can get.

But as you’d expect anyone as regal as Kate Middleton and Prince William to do, the British duo decided to thank a few extra-special fans with an extra-personal gift: a typed letter along with a personal photograph of the Duke and Duchess on their trip to Bhutan last year. Twitter user Paul Radcliffe was one such lucky fan, and he shared a shot of the snail mail on Twitter. (Is that ironic?) In the tweet, where he shared a picture of the goodies below, Radcliffe said, “Lovely Photo-Thank You Card arrived from the Duke & Duchess of Cambridge for their 6th Wedding Anniversary📬 📷 Lovely image by @ArthurJEdwards,” as reported by InStyle.

If you look closely, the note reads: “The Duke and Duchess of Cambridge are most grateful to you for the message you so kindly took the trouble to send on the occasion of their 6th Wedding Anniversary. It was most thoughtful of you and Their Royal Highnesses send you their warmest thanks and best wishes.”

If that’s not the classiest thing ever, then what is? Oh right, that throwback wedding-day Instagram, in full, below.
